AUTOMATIC GRAlNfMEASURE.

sPEcIFIcA'rIoN forming part of Letters Patent No. 282,063, dated July31, 1883.

Application filed February 13, 1883. (No model.)

To @ZZ whom may concern.-

Beit known that I, VILBER R. DUNKEL, residing near the town of Macon, inthe county of Macon and State of Illinois, have invented certain new anduseful Improvements in Automatic Grain-ll/Ieasures, ot' whichy thefollowing is a speciiication.

The obj ect of my invention is to produce a cheap and effectivegrain-meter that may be readily attached to the discharge-spout of aseparator.

My invention consists in the peculiar construction of thegrainreceptacles, together with the device used to regulate thedischarge of the same. l

In the drawings accompanying` and forming a part of this specification,Figure I is a side elevation of Iny device. Fig. 2 shows a side of thecasing with scale-beam and adjuncts detached. Fig. 3 shows the oppositeside of Fig. l, and Fig. 4 is a vertical section of Fig. l through thecasing and grain-receptacles.

a is the casing, provided with segmental projection a.

b b are circular disks th at fit against the sides of the casing, inwhich they are pivotally supported, while the space they inclose isdivided into sectors by partitions g g g g. The shaft of disks b pivotson the scale-beam side in a vertical slot, as shown at f in Fig. 2, andis pro-A vided with blockc, against the lower side of which scale-beam dpresses.

e is a projection on the casing that prevents block c from rotatingwhile the shaft is in the upper part of slot f.

hy shows a register attached to the casing on j the side opposite to thescale-beam.

As shown in Fig. I, the receptacles are empty and the shaft is in theupper portion of slot f. In this position, if grain be admitted into thedischarge-spout a, it will be supported by the inwardlyprojecting planeg, while the upwardly-projecting plane will close the vcrtical openingin the casing and form a complete receptacle for said grain. As thegrain accumulates its weight gradually lowers the block c until it isfree from projection e, and as the accumulation continues the weightfinally overcomes the pressure of the scale beam on the block, and thereceptacles rotate and discharge the grain. When the grain isdischarged, the scale weight immediately causes the shaft to rise to theupper part of slot f, whereby the block comes in contact with projectione,k and causes an absolute stop with another plane in correct positionto receive the grain.

The above process may be continued indefinitely, discharging an equalamount of grain each time, and the amount of grain discharged may beregulated by shifting the weight on the scale-beam.

I claim- The combination, in an'automatic grain-meter, of block o,scale-beam d, disks b, provided with partitions g, and casing a, (t,provided` with oblong bearing f and projection e, as and for the purposeset forth.
